tonsil

One of the masses of lymph tissue at the back of the throat that help fight germs entering the mouth and nose.

TON-sul noun

What it means

Usually the word means the palatine tonsils, the two oval lumps on each side of the back of the throat. They are part of the lymph system and trap germs. Inflamed tonsils are tonsillitis. When infections keep coming back or the tonsils block breathing during sleep, they may be removed (tonsillectomy).

For the nurse

After a tonsillectomy, the main danger is bleeding. Watch for frequent swallowing, which can mean blood trickling down the throat, and give cool fluids, avoiding red-colored drinks, straws and hard foods.
